The Maine Public Utilities Commission’s report studying the health issues surrounding so-called smart meters was posted on the agency’s website this week. It said the scientific evidence it reviewed on the issue is inconclusive and it found no credible, peer-reviewed studies to show a direct health risk from smart meters.

CMP installed the digital meters for more than 600,000 customers. The utility says the meters help it respond faster to outages and save money by eliminating the need to send workers to read meters.
